useful Improvements in Type Casting and Composing Machines; and we .do hereby declare the following tobe a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the characters of reference marked thereon.

This invention relates to pattern con trolled type casting and composing machines of that class wherein a plurality of matrices are movable in two directions at an angle to each other to bring any matrix to position .in accordance with the signals of the pattern: when thus positioned a selected'matrix is made to register with the casting cavity of the mold so that 'when the type metal pumping mechanism is operated, a type is cast bearing the face determined by the par the character or symbol forming the face of the-type. The machines are also provided with means for removing the type from. the mold and carrying it tothe galley and with means for giving a step-by-step movement to the pattern or controller which latter 1s conveniently in the form of a paper strlp having signals in the form of perforations usually made by asuitable keyboard perfo rating machine separate" from the casting machine. It will be understood also that there are other mechanisms and functions in a casting machine of this kind, which need not be referred to here, and that all of the operations .are properly timed so as to pro duce a harmoniously perative machine. Such a machine is. well'known tofthose skilled in the art, the best known commercial form thereof beingshown, as to its general organization, in Patent No. 625,998 to John Sellers Bancroft, dated May 30th, 1899. h

The main object of this invention, gener- J ally speaking, is to enlarge the capacity of Snnnnns BAN machines of .the above mentioned class so that they may include in their functions the casting and setting of type of larger sizes than heretofore within their usual capacity while at the same time their present-day functions are in no wise restricted or otherwise interfered with. Another object is the provision of controller mechanism to govern certain functions of the machine under certain conditions set up by the signals in the pattern whereby an inharmonious functioning due, for example to an error in the pattern, is prevented. These objects will be.

clearly set forth in connection with the following description of the embodiment of the mvention shown in the accompanying drawings in which description other objects will be particularly pointed out or will otherwise appear. l

It is sufficient for present purposes to point out some of the parts of the machine for identification purposes and to refer to the parts thereof oooperating and coacting with the mechanism which is more particularly a part of the present invention. For example, the following elements may be identified by referring principally to Fig. 1, the matrix case 1 and the means for positioning it comprising the side group of air pins 2 and the front group of air pins 2, said pins being selectively operated pneumatically in accordance with the signals of the pattern or record strip fed by a step-by-step movement in paper tower 8, each pin 2 projected upward serving as a stop for the side pin jaws 4 and each operated pin 2 as a stop for the front pin jaws 41, both sets of pin jaws being operated from cams connected with the bell crank lever 5, and each set of pin jaws 4, 1', serving to position locking bars 6, 6 (Fig. 11) the upward projecting portions of which serve as stops to position the matrix jaws 7, 7, which latter are also operated by the bell crank lever 5 in such a manner that they come together toward the stop while the pin jaws 4;, 41 having positioned the step, are moving outwardly preliminarily to closing upon the air pins set up by the next pattern signal. The matrix jaws are connected with the matrix case so as to position the latter in two directions at right angles to each other, since the side group of pins, pin jaws, locking bar and matrix jaws 'oper ate at right angles to the front group of similar elements. Other parts shown are the centering pin 8 for engaging with the matrix after it has been positioned to retain it in such position: the bridge 9: the centering pin lever 10: the hand wheel 11 on the shaft 12: the mold 13 and the mold blade operating rod 14: the mold dimensioning wedge 15 (Fig. 11) itself positioned in accordance with the signals of the pattern by the front matrix jaws 7 which, as before stated, are connected with the matrix case.

The above mentioned elements are substantially the same as disclosed in the patent jaws being brought together at a place corresponding with the particular pin 2, elevated in accordance with the signals of the pattern. For communicating this setting to the matrix case, a connection is provided as follows: Between the jaws 7 and adapted to be moved by them'is a head 20 on a sleeve 21 extending through one of the jaws 7 away from the matrix case and being fastened at its outer end to one end of the lever 22 the opposite end of which lever is provided with a pin 23 pivotally and slidably .held between the parallel cross head bars 21 slidably mounted by cross head connectors 25 in the guides 26 of the cylinder 27. The latter is suitably mounted on the main frame of the machine and has its axis generally parallel with the sleeve 21. The cylinderis intermedi'ately slotted so as to permit the cross bar 28 to extend through it, said bar being bolted at its ends to the parallel cross head connectors 25, bolted at its parallel bars 24 so as to connect said bars with the bar 28. Each end of the cylinder is provided with conduits 29, 30 in communication with its interior, and with pistons 31, 32each provided with an axial projection extending toward the cross bar 28 so as to hold the latter between them and to force it in one direction or the other according as air under pressure is admitted to conduit 29 or conduit 30 (Fig. In practice air is admitted to operate first onepiston and then the other, the operation in both directions, which of course alsooperates the cross bar 28, the connectors 25, and the parallel cross head bars 24, taking place during a single revolution of the machine. thus reversing the air under pressure will be described hereinafter. 1

Coaxial with and within the sleeve 21 is the draw rod 33 connected at one end to the cross slide 31 into the groove of which the matrix case or slide 1 hooks in the usual manner, and connected at the other end to the lever 85, the length of which is the same as that of lever 22 and the opposite end of which is connected by the links '36 to a fixed part of the cylinder 27. The two levers 22 and 35 are co-nveniently'made each of two parallel bars held in separated relation (Fig. 8) and are connected by a link37 at an intermediate point, as for instance approximately one third of their length from their connections with the sleeve 21 and the draw rod 33 respectively. 7

During each revolution of the machine air under pressure is admitted alternately to conduits 29 and 30. When air is admitted to the conduit 29 and exhausted from the conduit 30, it forces the piston 31 to the right (Fig. 6) and with it the cross bar 23,

the cross head 24: and the upper end of lever 22, the limit of this motion being dependent upon whether or not the movable gage block 38 (Figs. 7, 8 and 11) is or is notbetween afixed part of the ylinder 27 and the cross head 24. When the gage block 38 is positioned between these parts the cross head 24 is stopped when it strikes against the gage block and presses it against the fixed part of the cylinder. In this position-of the parts the levers 22 and 35 are parallel, with the result that .a movement of the sleeve head 20 by engagement with the matrix jaws 7 is communicatedunchanged to the draw rod 33 and the matrix case 1. In

other words there is .no relative movement between the sleeve head 20 and the draw rod 33, and conditions are exactly the same as though the said head were riveted or otherwise fixed to the draw rod, a condition and construction which obtains in the mechanism of the Patent 625,998, above mentioned. The machine may be said to be in normal operating condition, therefore, when the gage block 38 is positioned to serve as a stop for the cross head 24. Under such operation obviously aposition o-f the matrix case is assumed which corresponds precisely with the signal of thepattern.

-When air is admitted to the conduit 30 and exhausted from the conduit 29 the piston 32 is moved to the left (Fig. 6) andwith it the ross bar 28, the connectors 25 and the cross head 24 so as to move the upper end of lever 22 to thelei't. This, as is clear, releases the gageblock 38 and gives the opportunity of removing it, if desired, from between the cross head 24 and the fixed abutment. The removal is accomplished by admitting air under pressure to the conduit 39 leading to cylinder 40 in which there is a piston 41 the exterior face of which engages with the endof the gage block lever 42 which end is opposite to the end provided with the gage block 38. The gage block lever 42 is intermediately pivoted to the cylinder27 or to the frame for securing the cylinder to the main frame ofthe type casting machine; and the cylinder is also secured to said frame. A spring 43 fastened to the frame and the lever 12 serves normally to maintain the gage block 38 in its stop position. When air under pressure moves the piston 41 the-withdrawal of the stop to its inoperative position is brought about,'it being obvious that the timeof pro' ducing this effect must correspond with the time during which the gage block is released v. the retreating movement of the'cross head 24..

chine of the patent.

When the gage block is retained in with drawn or inoperative position, while air under pressure is permitted to operate through conduit 29 on piston 31 to move cross head 24: to the right (Fig. 6), such movement will continue until the cross head has reached the fixed abutment of the cylin' der wall 27 In this position the levers 35 and 22 are not parallel their upper ends being thrown apart out of parallel to the extent of the thickness of the gage block 38 and their lower ends being closertogether by a distance proportional to this thickness, as shown approximately one-half of such thickness since the link 37 is positioned about one-third of the lengths of the levers away from one end thereof. This relative movement of the levers causes a relative movement of the sleeve 21 and its head 20 with respect to the draw rod 33, the amount of relative movement obviously being pro portional to the thickness of the gage block. It will easily be understood from this that the matrix case, secured to the draw rod 33, will therefore be positioned, under these conditions, at a point which does not correspond with the position of the sleeve head 20, the latter corresponding, of course, exactly with the signals of the pattern. If it is assumed that the block 38 is two-tenths of an inch in thickness, the positionof the'matrix case will be one-tenth of an inch out .of normal position, ifthe link 37 is secured to levers 22 and 35 at a point one-third of their lengths from their connections with the sleeve 21 and the draw rod 33 respectively.

The front matrix positioning means is quite similar'to the side matrix positioning means above described. While the supplemental levers 22 and 35 and other parts of the latter means are, in the embodiment shown, in a horizontal plane, it was found desirable on account of the general construction of the machine, to place the corresponding elements of the front positioning means in a vertical plane. In describing this front means, a number of parts which correspond in function to those of the side means will be referred to by similar reference characters, provided, however, with an exponent.

The front pin jaws 4- when brought to a definite position determined by the particular pin 2' thrown up in accordance with the signals of the pattern, correspondingly locate in their movement not only the lock ing rack 6 but also certain mold dimensioning devices represented in Fig. 11 bythe wedge 15 so that these elements serve as setting means forthe mold dimensioning devices as well as setting means for the matrix and its case. This action is, of course, the familiar working of thewell known ma- On the subsequent spreading apart of the pin jaws i, the ma trix .jaws 7 which are also a part of the setting means, are brought together to the same point, being stopped by contact with the previously positioned locking rack 6, this occurring in the well known manner, also. In their movement together the matrix jaws 7, position the head 20 on the sleeve 21 extending through one of the jaws 7, away from the matrix case and being fastened at its outer end to one end of the lever 22,the opposite end of which lever is pivoted to a fixed wall of the cylinder 27.

Coaxial with and within the sleeve 21 is the draw rod 33 connected at one end with the matrix case 1 and at the other end with the lever 35, the length of which is equal to that of lever 22, and the opposite end of which is provided with a pin 23 pivotally and slidably held between the parallel cross head bars 24 slidably mounted by the cross head connectors 25 in the guides 26 of the cylinder 27. The latter is suitably mounted on the main frame of the machine and has its axis generally parallel with the sleeve 21. The cylinder 27 like cylinder 27 is slotted and fitted with a cross bar 28 secured to the connectors 25' and is provided with conduits 29, 30 and with pistons 31, 32. The operation of the pistons 31, 32, cross head 24 and associated parts is like that of the corresponding parts of the side matrix positioning means. The two levers 22 and 35 are connected by a link 37'; as shown this connection is approximately one-third of the lengths of the levers from their connections with the sleeve 21 and the draw rod 33 respectively;

During each revolution of the machine air under pressure is admitted alternately to conduits 29 and 30, thus forcing the p'istons 31, 32 alternately to move back and forth the cross head 24 and the end of the lever 35 coacting therewith, similarly as alternate admissions of air under pressure in the cylinder 27 shifts the cross head 24 and the lever 22 back and forth. The limit of reciprocation of the cross head 24 in one direction depends upon whether or not one or both or neither of the movable, stepped gage blocks 38, 38 is positioned between a fixed wall of the cylinder head 27 and the cross head 24. In this construction the cross head 24 does not abut directly against the fixed wall of the cylinder or against the gage blocks but has an abutting extension 24 which accomplishes this function. Normally the large step of gage block 38 is positioned between these parts, as shown, in which position the levers 22 and 35 are parallel so that a movement of the sleeve head 20 by engagement with the matrix jaws 7 is communicated unchanged to the draw rod 33 and the matrix case 1. In other words there is no relative movement be tween the sleeve head 20 and the draw rod 33, and conditions are exactly the same as though the said head were riveted or otherwise fixed to the draw rod as in the patent referred to. The normal operation obtains, therefore, according to which the matrix case is positioned correspondingly to the dimensioning wedge, both assuming position in accordance with the signals of the pattern. 1

The forcing of the extension 24 against the cylinder or against a gage block takes place when air under pressure is admitted through conduit 29 to act on piston 31: When, reversely, air is caused to traverse the conduit 30 to act on piston 32, the cross head 24 and its extension 24 are moved away from the cylinder 27 sufliciently to give freedom of cross movement to the gage blocks so as to permit them to be withdrawn from or placed in the path of movement of the extension 24". The stepped gage block 38 is moved by admitting air under pressure through conduit 66 into cylinder 40 in which there is a piston 41 connected'with the lever 42 (Fig. 2) having the'gage block 38 on its end, this lever being operated by the motor piston 41 to move the block from its normal position in which its large step is in the path of movement of the cross head extension 24 to either of two positions, one of which is that in which the small step of gage block 38 is in such path and the other inoperative position is that in which neither of said steps is in such path. A spring43' connected with the casting 44 containing the cylinder and with said lever intermediate of its connection with the piston 41 and its approximately central pivotal point at which it is pivoted to said casting by means of the shaft 45 tends to maintain said lever with the block 38 in normal position. 7

The stepped gage block 38 is moved by admitting air under pressure through c0nduit 67 into cylinder 40 (Fig. 2) in which there is a piston 41" connected with the lever 42 pivoted to the shaft 45 along side of lever 42 and having the gage block 38 on its end, this lever being operated. by the motor piston 41" to move the block from the normal, inoperative position, asshown, outside of the path of movement of the cross head extension 24" to either the position in which the small step or the large step of the gage block is in such path. A spring 43", similarly to spring 48 for lever 42, tends to hold said block 38 in normal inoperative position. A U-shaped member 46 is also pivoted to said shaft 45 at the ends of its arms, its connecting portion crossing above both of said levers 42, 42 and serving to stop their motion under their motors. This member 46 is capable'of being positioned manually in a position in which it stops motion of said levers so as to restrict the movement of gage block 88 from its normal position in which its large step is in the path of extension 24 to a position in which the small step is in such path and to restrict the movement of gage block 38 from its normal position outside of the path of extension 24" to a position in which the small step is in such path; and the member 46 is also capable of being -manually positioned in a stop position restricting the motion of gage block 38 from normal position to a position in which said block is outside of the path of extension 24 and restricting the motion of gage block 38" from normal position to a position in which its large step is in such path. The means for accomplishing such manual adjustment of the member 46 in these two positions consists (Fig. 2) of a pin 47 extending outwardly from the connecting portion of the member 46 and adapted to be sprung into either of two properly located holes in a spring lock member 48 secured to the casting 44. It may be here stated that the first position of adjustment, in which the pin 47 is in the lower hole of the spring member, corresponds with a variation of position of gage blocks 88, 38 which amounts to the thickness of one step in plus and minus-directions from normal and the second position of adjustment, in which the upper hole of spring member 48 is used, corresponds with a variation amounting to the thickness of both steps, plus and minus from normal. If the thickness of each. step is assumed to be twotenths of an inch, the variation in the first ad ustment is two-tenths of an inch in each direction and the variation in the second adjustment is four-tenths in each direction. If, furthermore the link 37 is positioned at one third of the length of the levers 22 and 35 from their connections with the sleeve 21 and draw rod 33' respectively, the above variations will represent a variation in the matrix case position in each direction of one-tenth for the first adjustment and two-tenths for the second adjustment. The communication of the variation due to the gage block positions, to the matrix case through the levers 22 and 35 is in all respects similar to what has been described with reference to the side matrix case positioning means. The one-tenth matrix position variation is suitable for a matrix arrangement of sizes capable of 18 point composition on the well known machine to which the invention has been applied and the first adjustment of the member 46 with its pin 47 in the lower hole of spring lock 48 may be termed the 18 point composition adjustment. The two-tenths matrix position variation is suitable for 24- pt. composition and the second adjustment in which the pin 47 is in the upper hole of spring member 48 may be termed the adjustment for 24 point composition.

In Fig. 11, the blocks 88, 58 are con nected with their motors 41 and 41 in a tons 41' modified fashion adapted to indicate the operation more clearly than if the mecha nism of Fig. 2 were drawn into said Fig. 11. In the mechanism of Fig. 11 the pisand 41" are connected to bellcrank levers 42 and 42 the other ends of said lever being connected by rods 38 and 38- with the gage blocks 38 and 38 respectively. A bar 47" adapted to be manually placed in either the lower or upper (as shown) holes in the uprights 46 serves as a stop for the bell crank levers 42 and 42 to vary their movement and consequently that of the gage blocks 38 and 38 for either 18 point or 24 point composition.

The mechanism for controlling the admission of air under pressure to cylinders 27 and 27 is shown in Figs. 1 and 11. The shaft 12 is provided adjacent the hand wheel 11 with a cam 50 on the surface of which operates the roller 51 on bell-crank lever 52 pivoted to avalve frame 53 secured to the machine frame. The end of the bell crank lever 52 opposite to the end provided with the roller 51 operates a valve of suitable construction, which may be the same as that disclosed in detail in the Patent No. 944,405 to ourselves,

dated December 28th, 1909 whereby air under pressure from a suitable supply with which the conduit 54 is in communication is directcam portion of smaller diameter. The conduit 29 is in communication with previously described conduits 29 and 29 and the corn duit 30 is likewise in communication with conduits 30 and 30.

The shaft 12 is also provided with a cam 50 cotiperating with roller 51' on bell crank lever 52 pivoted to a valve frame 53 and operating a similar valve to admit air under pressure from conduit 54 to conduit 55 when the roller 51 is on the small diameter part of cam 50 and to exhaust air from said conduit 55 when said roller is on the large diameter part of the cam as shown. The last mentioned conduit leads to controller mechanism for governing the operation of the gage block operating motors 41, 41 and 41, as will shortly be described. The bell crank levers 52 and 52 are connected by a spring 56 in such a way that both rollers are yieldingly pressed upon their cams. The

levers are also provided each with a later the lateral pins of the bell cranks have r0- ta-ted the latter against the spring 56 to an inoperative position in which the rollers 51, 51 are maintained out of contact with their respective cams: Or the member 5'2 may be moved to a lower position in which, as shown in Fig. 11, it has no effect upon the bell crank levers or their operation. In the lower position of the member 57 the valves are operated by the cams While in its upper position a single position of the bell cranks is maintained in which the conduits 55 and 30 are exhaustedv and conduit 29 is open to air under pressure. This condition, as an inspection of Fig. 11 will make clear, maintains the cross heads 24: and 24 forced toward the cylinders 27 and 27 respectively. Due to the exhaustion of conduit 55 there is no operation through the controller mechanism to be described, of the gage block motors t1, 41 and 41 and consequently the gage blocks are in their normal positions, the levers 22 and 35 are held parallel and the levers 22 and 35 are also held parallel. Under these conditions, these being the conditions shown in Fig. 11, the matrix case 1 is positioned to correspond as in the well known machine, with the position of the mold dimensioning means, both positions being in accordance with the signals of the pattern.

The conduit 55 leads from the air reversing valve frame 53 to the front controller mechanism previously mentioned. This comprises a controller in the form of a sliding valve member 59 provided with three rows of signal perforations or ports 59, 59 and 59 and with an end lug 60 adapted to be engaged and positioned by the pin jaws 4 when they come together against a pin 2- operated from the pattern. The controller extends substantially parallel with the draw rod 33 and is slidably mounted in the controller casing 61 itself mounted on a bracket 62 (Fig. 33) secured to the machine frame and supporting also the cylinder 27. The conduit 55 leads directly to the front air chest 63 secured to the front valve casing 61 and from this chest air under pressure is adapted to pass through whatever air ports of the three rows 59, 59 and 59, in the controller 59 may be in register with the lower, intermediate and upper exit ports of the casing 61 which latter ports are connected with the conduits 65, 66 and 67 respectively. The conduit 67 leads from the valve casing 61 to motor 41 for operating gage block 38", conduit 66 leads to motor 41 for operating gage block 38 and conduit leads to the side controller mechanism, to be described shortly.

Air chest 63 is provided, as shown in Fig. 9 with a gripper device which is pressed by the air under pressure in the chest againstthe controller 59, to hold it in its selected position and prevent leakage. The timing of air admission to the chest is such that the gripping effect takes place after the positioning of the controller. To accomplish this gripping function the chest 63 is provided with a piston 68 provided with a leather washer on its end for contact with the controller 59, the piston having a headed stem 69 extending toward the head of the casing 63, a central aperture 7 0 extending through the washer, piston and stem to a point below the stem head 69 at which point the aperture is connected with an annular recess 71 formed by turnin down to a smaller diameter the stem bellow its head. Surrounding the stem is a plunger 7 2 fittin the stem and the casing near its lower end and spring pressed toward the head of the air chest 63 by a spring 73 seated between an internal shoulder on the casing and a rim at the end of the plunger. The spring normally maintains the plunger and the piston because of the plungers engagement with the head of the piston stem against the head of the air chest 63 and holds the washer away from the controller so that the latter may be easily moved in the valve casing 61'. A groove is provided in the end of th stem head so that when air is admitted to conduit 55 it may readily flow into the air chamber above the plunger 72 so as to force it against the spring 7 3 away from the air chest head, this movement placing the annular recess 71 and the central aperture 7 0 in communication with the air chamber so that air may pass through whatever ports 59 59*, 59 may be registered with the eXit ports of the casing 61 and may thus pass through certain of the pipes 65, 66 and 67. At about the same time that air is admitted to the aperture 7 O, the end of the plunger 72 strikes against the piston 68 and moves it until it clamps tightly the controller 59. Itwill be observed that the clampino' effect automatically takes place practically simultaneously with the admission of air pressure to conduit 55 by the action of the pressure itself and that immediately upon the exhaustion of conduit 55 and the air chest 63 the controller is released by the action of spring 73.

hen air under pressure has passed through a controller aperture 59 into conduit 65 it is conducted by said conduitto a side controller mechanism comprising a controller 59 provided with a single row of ports 59 and a lug 60 adapted to be engaged and positioned by the pin jaws 4 when they come together against a pin 2 operated from the pattern. The controller 59 extends substantially parallel with the draw rod 33 and is slidably mounted in the controller casing 61 itself mounted on a bracket 62 secured to the machine frame and supporting also the cylinder 27. The conduit 65 leads directly to the side air chest 63 secured to the side valve casing 61' and containing a plunger gripping mechanism similar to that hereinbefore described in connection with front valve casing 61 andshown in Fig. 9 ofthe drawings. The casing 61 is, however, provided with only one exit conduit 39 which receives air which has passed from the conduit 65 through a controller signal port 59 and conducts it to the side gage block operating motor 41. The side controller mechanism may be termed secondary since it is itself under the control of the front of prialready been shown, in accordance with the signals of the pattern, their ports must be provided to correspond with the matrix case arrangement whereby one of more of the three gage block motors are operated or are not operated according to whether or not the matrix case must be moved difierentially with respect to the normal movement governed by the pattern; An arrangement suitable for 24 point composition is shown in Fig. 10, together with the corresponding front and side controllers 59 and 59 and mold dimensioning wedge member 15. The matrices 7 5 are viewed in plan their centering positions over the mold being represented by the cone holesillustrated by a cirole in each matrix. The plus marks on the drawing represent matrix positions which correspond with the signals of the pattern. The machine to which this invention has been applied, as hereinbefore described, normally contains square matrices measuring two tenths of an inch on the side, such a size being suflicient forcomposition up to approximately12 point: The number of matrices in the case is 225, there being 15 rows of 15 matrices for each row. The pin groups 2 and 2 correspondingly consist of 15 pins, each separated from its neighbor by two tenths of an inch. The dimensioning wedge moves, as has been shown, in consonance with the case in one direction and it therefore has 15 dimensioning positions, one for each of the 15 rows of matrices. The present invention is designed not to interfere in any way with the use of the machine in its usual scope of composition. It will be seen, however, that the individual matrices must be greater than two tenths matrices for composition larger than approximately 12 point. As shown in Fig. 10 the matrices for the 24: point composition illustrated measure two tenths by four tenths, two tenths by three tenths and four tenths square, as will readily be seen on the assumption that the plus marks representing the usual matrix positions as well as the present air pin positions are two tenths of an] inch apart. The number ofmatrices is, therefore, much less than 225 and the number of rows much less than 15. It is to be noted, however, that the mold dimensioning wedge has 15 positions as usual and that it may be positioned in any selected one of these fifteen positions by proper signals in the pattern. It is apparent, too, that a row of matrices need not be restricted to a corresponding position of the wedge as is necessarily the case when 15 rows of two tenth matrices are employed but that each row may have a plurality of wedge positions assigned to it to the end that from a row of matrices may be produced type of a plurality-of sizes in the set wise direction which is the direction of dimension controlled by the wedge.

It will be understood that if a plus mark corresponds with a cone hole in the drawing and the wedge position for that plus mark represents the desired set dimension of the type produced from the matrix having said cone hole, the machine will work in normal fashion: the slide controllers 59 and 59 will not permit operation of the gage block motors, the gage blocks will retain their normal positions and the matrix case will be moved without variation of its connections with the pairs of matrix jaws 7 and 7, themselves moved to pattern controlled position by the groups of pins 2, 2', pin jaws 4, 4 and stop racks 6, 6. For example, suppose the matrix A is for a type character the body size of which is, say, 5 units, such size'being represented by the wedge positionmarked 5 '(Fig. 10); then the pattern signal should cause the case to be moved so that the plus mark A is above the mold cavity. Since the matrix cone hole corresponds with the position A the type will be cast with a 5 unit body in the usual manner.

A few examples will be shown in'which the differential movement of the case is accomplished by the present invention. Suppose the matrix B represents a 6 unit char acter, then the position B will be indicated in the pattern and the wedge 15 will be brought to the position marked 6. However, the air pins for thus locating the wedge will also position the controller 59 so that the port 5913 is in register with exit conduit 67 leading 11) to gage block motor 41. When air under pressure is admitted to the air chest 63 it will pass through this port 59B to the said motor and draw the large step of gage block 38 in the path of the extension 24". lVhen the cross head 24- is moved toward the cylinder 27? the extension 24 will be stopped by the large step of this gage block and the levers 22 and 35 will be out of parallel sufficiently to cause a relative movement of two tenths of an inch between the draw rod 33 and the sleeve head 20. 'lVhen the sleeve head, therefore, is positioned to a position corresponding with the B position of the matrix case, the latter will have been displaced to the right (Fig. 10) two tenths of an inch: this brings the position B over the mold cavity and since this position B is identical with the cone hole of the matrix B the matrix has been properly positioned for casting a type having a 6 unit body. It will be noted that matrices A and B are in the same matrix case row, but that nevertheless they are caused to cast type of different body sizes.

Again, suppose the matrix C is to cast on an 18 unit body. The pins corresponding with position C are operated from the pattern and the case is positioned in the normal manner, there being no ports in controllers 59 and 59 corresponding with position C so that the levers 22 and 35 as Well as the levers 22 and 35 remain parallel and produce no relative movement between the sleeve heads and their respective draw rods; the operation is in all respects normal. Suppose, however, D is a 15 unit character; pins corresponding with position D are blown up, air under pressure passes through port 59D from conduit 55 to conduit 66 thus operating gage block motor 41 to withdraw gage block 38 entirely from the path of cross head extension 24". This extension, therefore, abuts the cylinder 27, there being no gage block in its path, and the sleeve head 20 is relatively moved two tenths of an inch with respect to the draw rod 33,

this movement being, as is obvious, in a di rection opposite to that just described for matrix B to the end that the matrix D is moved two tenths of an inch to the left (Fig. 10). This brings the position D over the mold cavity and since this corresponds with the cone hole of matrix D the latter is properly positioned for casting a 15 unit body type.

Suppose E to require a 11 unit body. The position E would be indicated by the pattern; air would pass through controller port 59E and then through conduit 66 to accomplish as for the matrix D, above, a movement of the matrix E two tenths of an inch to the left (Fig. 10), thus bringing position E over the mold cavity. Air would also pass through the controller port 59E and through conduit to side air chest 63 and thence through side controller port 59E and conduit 39 since this port 59E is positioned in register with the exit port leading to conduit 39 by the pattern controlled means for positioning the matrix E to E position. Pressure in conduit 39 operates gage block motor 11 to withdraw gage block 38 from between cylinder 27 and cross head 2 1 so that when the latter is moved toward the former it is not stopped by the gage block but abuts directly against the cylinder 27 with the result that the levers 22 and 35 are moved out of parallel tothe extent necessary for producing a relative movement of one tenth of an inch between the sleeve head 20 and the draw rod 33, this movement being in a direction such that the matrix case is moved downward (Fig. 10). By the control of port 59E in front controller 59 the matrix has been moved from E position to E position and by the control of port 59E of the side controller 59 it is moved from E position to cone hole position E In this position the type from matrix E is cast 11 units wide. It is clear that the same matrix position could produce type 12 units wide or 13 units wide according to the control indicated by the signal perforations in the controllers to which signals the motors of the gage block mechanisms are responsive; furthermore that each arrangement of matrices in the case requires a set of controllers in agreement with such arrangement. lVhen the matrix arrangement is altered, it is the practice to change controllers if necessary, the valve casings 61 and 61 being constructed in any suitable way so as to permit of easy removal of the controllers. In Fig. 4:, a plate and screw 7 6 are provided to close a slot in casing 61 in which slot the controller 59 is slidable, these parts being easily removed so as to open'the slot for the removal of the controller through the bottom of the slot. The side controller 59 may be provided with a similar device.

It may here be pointed out that the arrangement of controllers is in the nature of a signal device augmenting the scope of the paper pattern or controller; furthermore that the operation of this controller arrangement must of necessity be in agreement with the operation of the mold dimensioning means, so that, while a wrong signal in the pattern might set up a wrong mold dimensioning position, the controllers would insure a matrix position which would correspond with this wrong but nevertheless corresponding mold dimensioning position. Independent pattern signals for setting the mold dimensioning means and for positioning the matrix case might be out of harmony with each other due, for example, to an accidental tear or perforation in the paper, and this would result in a lack of harmony between the set width of the mold cavity and the size of the matrix positioned over it, and would be apt to result in a squirt or other improper operation. The controllers ofthis invention prevent this happening by insuring whatever the pattern signal, a corresponding setting ofmatrix and mold. It is obvious that the controller might be provided with other siginals than those for governing the, gage blocks so as to'control, for example, the entire magage blocks of any dimensions may be employed or blocks having any number of steps so as to displace the matrix case largely varying amounts.

The operation of the invention has already been described but a general rsum briefly sketched, will perhaps be valuable at this point. The machine as a whole operates, of course, in the Well known fashion, the pattern feeding, matrix positioning, casting, type delivering and other operations taking place in properly timed relationship. The connections between the matrix and the matrix jaws consisting of the coaxial sleeves and draw rods and the groups of levers 22 35 and 22, 35 have been described and it ias been pointed out that when the gage blocks are in their normal positions as shown (Fig. 11) the levers 22 and 35 are parallel and the levers 22 and 35 are also parallel, and that under these conditions the matrix case is positioned to correspond precisely with the signals of the pattern, the effect being the same as if thesleeves and draw rods were fixedly secured together. When, how ever, a gage block is moved out of normal position and the levers 22, 35 or 22, 35 are thrown out of parallel a relative movement between a draw rod and its sleeve occurs to vary the movement of the matrix case. This variation in one direction as governed by the side gage block, is one tenth of an inch taking the dimensions hereinbefore used as an example: the variation in the other direction at an angle to the first direction is governed by the front gage blocks and amounts to one tenth of an inch plus or minus if the blocks are adjusted to throw levers 22' and 35 out of parallel the amount of one step of the blocks and to two tenths of an inch plus or minus if the blocks are adjusted to throw said levers two steps out of parallel. The operation of the lovers by the cross heads 24: and 24 is accomplished by the pistons 31, 32 in the cylinder 27 and the pistons 31, 32 in the cylinder 27 The pistons 32 and 82 are moved to force the cross heads away from their cylinders, thus leaving the gage blocks free for movement, by air under pressure admitted into conduit 30* and thence in conduits30 and s5 30 connected with the cylinders 27 and 27 respectively. The timing of this admis sion is accomplished by the cam 50 (Fig. 11) which is so placed as to admit air to the conduit 30* after the matrix jaws have begun to open and the pin jaws have begun to close: the conduit 30 is exhausted by the reversino of the valve and the consequent movement of the cross heads in the opposite directions is accomplished when the cam roller 51 runs off the high surface of the cam 50, the latter being constructed so that this takes place at about the time that the matrix jaws begin to close and the pin j aws begin to open.

The front gage blocks 38',38" are operated by motors 41, 41', energized by air under pressure in conduits 66 and 67. Air is admitted into these conduits through controller 59' at a time subsequent to its being positioned by the closing of the pin jaws and while the latter are closed. Air is admitted to the air chest 63 through conduit 55 timed by the cam 50 which is so placed on-the shaft 12 as to operate the air admission valve to admit air from conduit 5 to conduit 55 after the pin jaws have come together, which means after the controller 59 has become positioned. At this time, the

cross heads are of course in position to allow of movement of the gage blocks. U11- der proper conditions air also will traverse a port of controller 59 to enter conduit 65 leading to side controller 59 the positioning of which is of course simultaneous with the positioning of controller 59 this pressure will traverse a port of controller 59 under proper conditions and will pass through conduit 39 to operate side gage block motor 41. The cam 50 is constructed so as to exhaust conduit 55 before the pin jaws begin to close totheir next position, thus preventing air from reaching the air chests 68, 63 during-the movement of the controllers 59, 59. When the air chest 63 is exhaused the spring 73 therein will Withdraw the piston 68 from clamping contact with the controller 59. 1 The latter is now loose and can be easilymoved: moreover, this looseness permits of the exhaustion of conduits 65, 66 and 67. Exhaustion of conduit 65 effects a loosening of controller 59 and con sequent exhaustion of conduit 39.
